[ Upstream commit ba569fb07a7e9e9b71e9282e27e993ba859295c2 ]
Commit 227619c3ff7c ("can: m_can: move runtime PM enable/disable to m_can_platform") moved the PM runtime enable from the m_can core driver into the m_can_platform.
That patch forgot to move the pm_runtime_disable() to m_can_plat_remove(), so that unloading the m_can_platform driver causes an "Unbalanced pm_runtime_enable!" error message.
Add the missing pm_runtime_disable() to m_can_plat_remove() to fix the problem.
